Review Meta Analysis
Prognostic significance of elevated troponin in non-cardiac hospitalized patients: a systematic review and meta-analysis.
Cardiac biomarker troponin can be elevated in patients without a primary cardiac diagnosis and may have prognostic value. We conducted a systematic review to estimate the prevalence and prognostic significance of elevated troponin levels in patients admitted to hospital without a primary cardiac diagnosis. Literature search was done using MEDLINE (1946 to November 2012), EMBASE (1974 to Week 45, 2012), and Cochrane Central Register of Controlled Trials (November 2012). ⋯ Elevated troponin was also associated with increased risk of long-term mortality at 6 months (9 studies, 5368 patients, OR 4.21, 95% CI 1.84-9.64, P < 0.00001). Troponin is an independent predictor of short-term mortality with a pooled adjusted OR of 2.36, 95% CI 1.47-3.76, P < 0.0003. In conclusion, elevated troponin in non-cardiac patients is independently associated with increased mortality.

Review Meta Analysis
Associations of prediabetes with all-cause and cardiovascular mortality: a meta-analysis.
Reports on the association of prediabetes with all-cause mortality and cardiovascular mortality are inconsistent. Objective. To evaluate the risk of all-cause and cardiovascular mortality in association with impaired fasting glucose (IFG) and impaired glucose tolerance (IGT). ⋯ Prediabetes, defined as IFG 110, IGT, or combined IFG 110 and/or IGT, was associated with increased all-cause and cardiovascular mortality.
